Mastication for the mind—The relationship between mastication and cognition in ageing and dementia
Neuroscience & Biobehavioral Reviews, 2011The goal of this literature review has been to investigate the relationship between mastication and cognition, with a special focus on ageing and dementia, and its possible underlying mechanisms. Since the relationship between mastication and cognition is not yet firmly established, and is investigated in the context of a number of different ...

Coordination of mastication and swallowing
Dysphagia, 1992The coordination of mastication, oral transport, and swallowing was examined during intake of solids and liquids in four normal subjects. Videofluorography (VFG) and electromyography (EMG) were recorded simultaneously while subjects consumed barium-impregnated foods.

Abstract Recovery of masticated rubber was measured at different temperatures. Recovery was found to be influenced, but not governed, by plasticity. A quick method, working at 100°, gave information on the influence of fillers and of storage at room temperature and at 70° C.

Abstract As has been shown, peptizing agents act in the mechanochemical and thermooxidative breakdown of elastomers as radical acceptors at low temperatures and as oxidation catalysts at high temperatures. Modern peptizing agents usually consist of thiophenols or aromatic disulfides combined with metal complexes (chelates) of Fe, Cu, and

Mastication. IX. Shear‐dependence of degradation on hot mastication
Journal of Applied Polymer Science, 1959AbstractA comparison between the viscosity‐molecular weight relationships for natural rubber degraded in thin films at 130 and 140°C. and on cold and hot mastication indicates a greater similarity of distribution on degradation by the mastication treatments.

A 56-year-old woman presented with episodic vertigo, dizziness, and diplopia during meals and prolonged verbal presentations at work. Subsequent work-up included an eventual catheter-based angiogram revealing an ostial left external carotid artery (ECA) occlusion with reconstituted retrograde flow via a variant collateral branch from the dominant left ...

Abstract Acetone-soluble substances formed during the milling of rubber were divided by chromatographic analysis into three fractions. Infrared spectra of these fractions were identical with the spectra of corresponding fractions from heat-aged raw rubber. The significance of these results is discussed in conjunction with Pike and Watson'

Abstract Probably from the beginning of the rubber industry no process has changed so little as that for softening raw rubber, its socalled mastication. Although Hancock's machine, the masticator (1826), consisted of an internal rotating roll and a stationary shell, and modern machines have two rotating rolls, the same principle has ...

The dynamics of mastication in pigs
Archives of Oral Biology, 1976Abstract Mastication in miniature pigs was studied via microphone recording and correlated electromyography and cinematography. The results were compared with data from the literature on man and the rhesus monkey (Macaca mulatta). It was concluded that anatomical similarities between pigs and higher primates are due to overall correspondences in ...

The posterior displacement of parapharyngeal fat differentiates tumors that originate in the masticator space (MS) from those originating in surrounding spaces. Most benign tumors originating in the MS are hemangiomas, lymphangiomas, osteoblastomas, or schwannomas.
